Smartwatch Interface Design for Low Power Consumption and Built-in High Performance

Mobile technology has provided us with many excellent benefits. Still, it may also have a detrimental influence when it demands our focus and diverts our attention away from the real world. Technology fades into the background if we make wise design decisions, enriching the here and now.

One strategy for designing for the future is to focus on the natural environment rather than technology. Many spent years attempting to make the virtual world resemble reality. However, the actual world around us gives a rich canvas to create with wearables and gadgets like smartwatches. It has a more excellent resolution and is more lifelike than any computer.

We need to build design experiences that allow us to create experiences that are still interesting but less distracting as smartwatches and wearables grow more mainstream. If you look at all the smartwatches available in the market, you’ll see that battery life is a significant selling factor for these smartwatches.

Smartwatches and other wearables are intended to be used regularly. As a result, they must be constructed so that the user need not charge the gadget often. 

Now, you can’t just increase the battery capacity because you need to keep the watch’s size and weight in mind. Plus, you cannot compromise on the performance to save power or it will have a negative impact among the buyers. 

So, the ultimate approach would be to make improvements to the user interface of the smartwatch in order to deliver excellent performance while ensuring that each full charge allows the smartwatch to run longer than its counterparts.

This article is aimed at providing you with some smartwatch interface design tips that might come in handy when designing a smartwatch that will deliver high performance and consume less power.

Making Use of Darker Colors

When it comes to smartwatch UI design, choosing dark colors saves battery life.

Darker colors always assist in keeping the power usage as low as possible, whether you’re utilizing an LCD or an LED panel.

Keep the backdrop dark while developing the menu and the remainings of the watch interface. Aside from that, you may use messaging to encourage viewers to save energy by switching to dark mode. However, ensure that the notifications do not appear frequently or are inconvenient.

Even when designing watch faces, darker hues might help you get more battery life.

Optimizing Display usage

Another excellent technique to save as much power as possible is turning down the smartwatch’s performance while not in use.

When creating a smartwatch user interface, ensure that system activity should be minimized when not engaging with their watch. 

Turn off the display when the gadget is not in use. There are two approaches to this. You may set a screen timeout, which shuts off the screen after a specific span while the watch is idle. You may also make a gesture. As a result, once the user places their wrist down, the watch display immediately shuts off. The latter solution is more sensor-reliant, but it can be more efficient.

Using the Standby Mode

When the watch controller is not in use, another approach to saving energy is setting it to standby mode.

A low-energy CC2541 wireless microcontroller, for example, can be used. When it can run only with the sleep timer and no longer requires Timer 1, the current to the controller is lowered from 90 microamps to just 0.6 microamperes.

As a result, while the gadget is not in use, you save more than 99 percent of the energy.

Aside from that, you may configure all of the background processes to be interrupt-driven. It will ensure that your watch’s microcontroller is always in sleep mode and will only wake up when a background function requires it.

Optimum Performance

For optimal battery economy, the smartwatch’s user interface must be optimized. You must understand how memory and graphics interact to get the most out of your wristwatch.

You could wish to use high-resolution photos in your UI to make the icons seem sharper, and the watch look more appealing overall. However, generating high-quality pictures necessitates the CPU cycles and RAM space needed to decode and display them.

Using high-resolution graphics in the UI is a waste of resources, money, and inefficient because these CPUs and RAMs are expensive and have limited resources. There are also animations which are expensive to create. Animated flicks are a hit with everyone, and users will seek a watch with several smooth and appealing animations. A lot of resources are required to produce beautiful animations. But these resources are too expensive to afford because of the expensive tools and technology put in. As a result, animations may make screen transitions more interesting for users. However, keep in mind that it uses a lot of memory and slows down the process. So, Always keep track of how many animations you add to your smartwatch. Provide customers with the option of turning off the animations for increased efficiency and energy savings.

Final Thoughts

While creating a smartwatch, consider that smart gadgets work on low power consumption yet perform well. Always prioritize the use of darker hues in the user interface. Allow the watch to operate in standby mode most of the time. Also, wherever feasible, take steps to switch off the display. Finally, make the UI more power-efficient by removing high-resolution graphics and reducing the number of animations you utilize on your device.
